// 强调: 版本数字必须是v0.0.0 - v9.9.9； v小写，数字只能个位。
// 1. 获取远端版本号
// 2. 和本地版本比较 - 相同 - 退出OTA模式
// 3. 不同下载版本，分类cat1和mcu版本
// 4. 有mcu更新，发送版本给mcu。mcu 进入OTA模式
// 5. 有cat1更新，跟新 - 重启 - 
// according to FOTA通信协议.docx, 
// 1. get remote firmware version, compare with local --- FotaGetRemoteVer
// 2. download firmware, save as special named file, and verify it. --- FotaDownloadFirmware
// 3. restart for update.
// 4. update over and restart to report result. --- FotaReport
